Fatentecl July 11, 1933 UNITED STATES GEORGE I). SCHERMERHORN, FREADING, 'MICHI GAN CUSHION FOOT 7 Application filed March 2,

My invention relates to a detachable cushion foot particularly adaptedfor use in conjunction with folding chairs.

' An object of the invention is to provide a durable, inexpensivecushion foot which may readily be secured to the extremities of chairlegs of various types and which may be inexpensively manufactured inlarge quantities.

A further object of the invent-ion is to so associate the cushioningsubstance with a metallic foot that there is substantially nopossibility of its tearing away therefrom and to so form the metallicfoot of a plurality of parts that it is of rigid construction andconstitutes a mold about which the cushioning substance may be formed insitu.

Further meritorious features of the invention reside in the particulararrangement and combination of parts to be described hereinafter inconjunction with the accompanying drawing wherein like numerals refer tolike parts throughout the several figures and wherein:

Fig. 1 is a side elevation of a chair utilizing the improved footstructure,

F ig. 2 is an elevation, partly broken away and in section, of the footpositioned at the extremity of a chair leg,

Fig. 3 is a section along 33 of Fig. 2, and

7 Figs. 4 and 5 illustrate the composite units forming the metallic footassembly with which the cushioning substance is associated.

Referring now to the drawing, Fig. 1 il- .1 lustrates a conventionalfolding chair includ ing front and rear legs and 12 at the extremitiesof which are positioned cushioned feet 14 of the improved type to bedescribed hereinafter. Each of the chair legs may comiprise a metallicstrip 16, the longitudinal edges of which are rolled over into tubularform as illustrated at 18 and 20.

The metallic'port-ion of the cushion foot assembly includes a cap member22 illustrated in Fig. 5, which cap is elongated as illustrated andprovided with a depending flange 2a extending from its peripheral edge.A longitudinal slot 26 is formed in the top of the cap, ofiset from thecenter thereof, and

0 extends parallel to the edge thereof throughout a substantial portionof its length.

The other metallic element (Fig. 4) com prises a web portion 28 beveledas at 30 across its upper extremity and turned laterally at the basethereof to form a flange 32. As

hitherto stated, the slot 26 is offset from the center of the cap 22 andthe width offlange 32 is substantially equal to the distance betweenslot 26 and the furthest removed edge of the cap 22. r

The central portion of the edge of flange 32 is cut away in ovalformation as illustrated at land apertures 36 and 38, centering upon theturned over portion 40, are provided. A lug 42 is struck outwardly fromthe web portion 28 and extends parallel to the flange 32. Its width isequal to that of the flange 32 and the upper portion thereof is adaptedto seat upon the inside of the cap member as clearly illustrated in Fig.3. An aperture is providedin the central portion of the. web 28.

In assembling the units the web 28 is inserted from the bottom throughlongitudinal slot 26 in the cap 22. The web, adjac'entits lowerextremity, is provided with protruions 4L6 and i8 which limit the extentto which the web may be forced through the slot, the protrusions beingadapted to seat,

against the underside of the top of the cap 22. It will be apparent thatthe upper portion of the lug 42 is in alinement with the protrusions 46and 48, which relationship permits the said lug'to seat snugly againstthe top of the cap. By reason of the oval cut away portion 34: the lug42 may readily be welded to the under face of the cap to form anintegral unit.

Having associated themetallic elements in the proper relative positionsome suitable cushioning substance is molded insitu about the flange 32and within the depending flanges 24 of cap 22. Preferably rubber isutilized and the resulting cushion is clearly illustrated at 50. Byreason of the particu lar position'of apertures 36 and 38, the rubber orother substance may readily flow therethrough in both a vertical andhorizontal direction. This facilitates the rapidmolding of the cushionfoot 50, the opening 52 provided by the turned up lug 4L2 assisting inpermitting free flow of the rubber during the molding operation.

The cushion foot now being complete, it may be readily inserted, due tothe beveled upper portion of the web 28, under the edges of the rolledover tubular portions 18 and 20 of the chair legs, the intermediate legportion 16 in each instance being preferably formed with a slight bulge5a which cooperates with the aperture 44 to retain the foot assembly inosition. The tubular rolls 18 and 20 may be subjected to additionalpressure subsequent to insertion of the foot assembly if necessary,although the locking action of the indentation 54 and the aperture 44will suflice.

Various modifications of the improved structure illustrated herein maybe apparent 10 to those skilled in the art and for that reason I wish tolimit myself only within the scope of the appended claims.

What I cla 1 A cushion foot assembly including, in combination, ametallic web provided with a laterally extending flange at one extremitythereof, and an aperture extending through the juncture of the web andflange whereby said aperture provides a vertical and a lateral passageand cushioning material molded about said end above and below saidflange.

2. A cushion foot assembly including, i combination, a metallic webprovided with a laterally extending flange at one extremity thereof,apertures extending through the juncture of the web and flange wherebyeach aperture provides a vertical and lateral passage, a cut awayportion extending from the outer edge of said flange, and a lug struckoutwardly from the web to a position substantially parallel to theflange, and cushioning material molded about said end above and belowsaid flange and between the flange and lug.

A chair foot including, in combination, an element comprising a webportion having a flange extending laterally away from one extremitythereof, and a lug struck up from said web portion to provide an openingin the web, said lug extending parallel to said flange and beingsuperposed thereover, and cushioning material molded about said flangeand between the flange and lug and extending through the aperture formedby the striking up of the lug.

4.
